4 Claims.

This invention relates to a liquid dispensing device designed primarily for use with the type of measuring apparatus used at filling stations for dispensing liquid fuel to automotive vehicles,

. but it is to be understood that the device, in accordance with this invention, is for use in any connection for which it may be found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a device of the type referred to so constructed and arranged to provide for a variable flow of the liquid therefrom when occasion requires.

A further object of the invention is to provide, in a manner as hereinafter set forth, a device of the type referred to which may be expeditious- 1y secured to the regular standard flexible hose leading from the liquid measuring apparatus.

A further; object of the invention is to provide, in a manner as hereinafter set forth, a device of the type referred to including a nozzle coupling portion, a combined valve chamber and handle part and a shiftablespring controlled manually operated Valve controlling means depending from said part and arranged forwardly of the front of the handle for controlling the dispensing action of the device.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a device for the purpose referred to which is simple in its construction and arrangement, strong, durable, compact, readily assembled, thoroughly etficient in its use, conveniently and expeditiously Opel? ated to provide a liquid dispensing function and comparatively inexpensive to manufacture. The

.35 channel is of large size at the inlet end where it connects with the supply pipe and gradually decreases in size throughout its length to the valve below described, and just beyond the valve is also. of small size, from whence it is greatly and immediately enlarged and so continues. to the exit. The result of this structure is that toward thecenter oi the device the flow is choked back and decreased in volume, but due to the enlargement of the exit a free passage is provided and 45 the flow not forced out but allowed to move quietly whereby turbulence and splashing is prevented.

To the above ends essentially and to others which may hereinafter appear, the invention 50 consists of the novel construction, combination and arrangement of parts as will be more specifically described and illustrated in the accompanying drawing; wherein is shown an embodiment of the invention, but. it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.

In the drawing:

Figure 1 is a side elevation of the device installed with respect to a liquid conducting line leading from a source of supply,

Figure 2 is a vertical sectional view of the device with the nozzle element thereof removed,

Figure 3 is a section on line 33, Figure 2, and

Figure 4 is a top plan view of the controlling lever partly in section.

The device includes a casting l formed of any suitable material channeled from end to end thereof. The casting I consists of a nozzle coupling portion 2, a valve chamber portion 3 and a handle or hand grip forming portion 4. The portion 3 couples the portions 2 and 4 together and is substantially of elbow-shape in lengthwise section. The portion 2 is straight. The portion 3- inclines rearwardly and depends from the rear end of the portion 3. The channel which extends from end to end of the casting I has the part 5 thereof arranged in portion 4, part 6 thereof arranged in portion 3, the lip or part 1 thereof arranged in portion 3 and the part 8 thereof arranged in the portion 2. The part 8 merges into the forward end of the part I and Y the rear end of the latter merges into the forward end of the part 6. The upper end of part 5 merges into the other end of part 6. The part 5 is disposed at an inclination with respect to the part 6. The latter is of curved contour and has its forward portion arranged above the rear of part 'I'. The part 8 is straight and opens at the rear end of its bottom into part 1. The part 8 is of greater diameter than the parts 5, 6 and l. The portion 3v of casting I. has an integral depending web 9 between the parts In and II of such portion. The web 9 aligns with the longitudinal median of portion 3 and is spaced from the side faces of the latter. The forward end of the wall of part 6 of the channel is bevelled as at [2 to provide a valve seat arranged at the top of part 1 of the channel and within the portion 3 of the casting. Directly below and spaced from the seat l2 the part I0 of the portion 3 of the casting is formed with a vertically disposed valve chamber I3 which opens into the part I of the channel and also opens at the bottom of the part ill of portion 3 of the casting. The outer portion of the wall M, of valve chamber I3 is threaded as at [5 and engaging therewith is an outer packing gland l6 formed at its inner end with an inwardly extending annular flange 11 and at its outer end with an outwardly directed annular flange l8. The gland I6 is interiorly threaded and engaging therewith is a peripherally threaded inner packing gland l9 having an external flange 2D abutting flange l8.

Extending through the glands l6 and I9 is a stern 2| formed with a circular head 22 of a diameter to snugly engage the wall M of valve chamber |3. Fixed to the top of head 22 is a bevelled disc-shaped valve 23 adapted to engage the seat |2 for the purpose of closing part 8 of the channel to part 1 f the latter. When the valve 23 is off its seat, communication is established between the parts 6 and of the channel of the casting. The stem 2| is of a length to project beyond the gland l9 and carries at its outer end a diametrically extending pin 24. Interposed between the flange ll of gland l6 and the inner end of gland l9 and surrounding stem 2| is a packing 25.

The device includes a nozzle 26 which is interiorly threaded and engages with the peripheral threads 2'! formed on the portion 2. The latter has an annular stop or rib 28 on its periphery on the inner end of the threads 21.

The device includes a shiftable spring controlled manually operated controlling lever 29 for the valve structure consisting of the stem 2|, head 22 and disc 23. The lever 29 is of angle form and consists of an upper horizontally extending leg 30 and a vertically disposed leg 3| depending from the inner end of the leg 39. The leg 30 has a bifurcated forward end 32 provided with aligning slots 33 and at its rear end is formed with a pair of ears 34 having aligned openings 35. The inner face of the leg 3| is formed with a groove 36 extending lengthwise thereof. The pin 24 projects laterally in opposite directions from the stem 2| and is slidably mounted in the slots 33. The lower end of the stem 2| is positioned in the bifurcated end 32 of the leg 39. The web 9 is formed with an opening 31 which aligns with the openings 35. A pin 38 extends through the aligning openings 35, 31 for pivotally connecting the rear end of the leg 39 to the portion 3 of the casting I.

The forward side of the portion 4 of casting I has a groove 39 lengthwise thereof and which opposes the groove 36. Arranged between the leg 3| and the front of the portion 4 of casting is a spring 49 formed of a looped part 4| and a pair of end parts 42, 43 extending in opposite directions with respect to each other. The end part 42 bears against the wall of the groove 36. The end part 43 bears against the wall of the groove 39. The spring 40 functions to normally maintain the valve structure in position to shut off communication between parts 6 and l of the channel in casting The valve structure is slidably connected to the lever 29 or in other words, there is a loose sliding connection between the lever 29 and the lower end of the stem 2|. When rearward pressure is exerted against the leg 3| of lever 29 the leg 33 is lowered which in turn will force the valve structure downwardly and the extent of the shift will provide for varying the flow of the discharge of the liquid from the casting into the nozzle 25.

With reference to Figure 1 a fluid conducting line is indicated at 44 and is attached to the portion 4 of the casting The disc 23 is to be constructed of any suitable material and is anchored to the head 22 by the holdfast means 45.
